Method development and limitations are discussed.Sucrose plays crucial roles in growth and responses of plants to the environment, including those in ornamental species. During post-harvest handling of cut flowers, sucrose degradation is an essential process of inter- and intra-cellular carbon partitioning affecting flower opening and senescence and, subsequently, flower quality. However, complete information about the molecular basis of sucrose degradation in ornamental flowers, which can be catalyzed by two kinds of sucrolytic enzymes, invertase (INV), and sucrose synthase (SUS), is not available from past reports. The present study shows that sucrose treatment of carnation (Dianthus caryophyllus L.) florets increased starch content in petals, accompanied by decreased vacuolar INV (VIN) activity and increased SUS activity. However, hypoxic treatment of carnation florets decreased sucrose content and cell-wall INV (CWIN) activity in petals. In silico analysis using the carnation genome database identified six CWIN, three VIN, eight cytoplasmic INV (CIN), and five SUS genes. Real-time RT-PCR analysis confirmed that these genes are differentially expressed in carnation petals in response to sucrose and hypoxic treatments, partially corresponding to the changes in enzyme activities. In contrast to DcSUS1 (Dca4507.1), a SUS gene already reported in carnation, which showed preferential expression under aerated conditions, the expression of DcSUS2 (Dca22218.1), an undescribed carnation SUS gene, was enhanced under hypoxia similarly to an alcohol dehydrogenase gene DcADH1 (Dca18671.1). These results suggest that sugar metabolism in carnation petals is regulated in response to environmental cues, accompanied by modulated activities and gene expression of a set of sucrolytic enzymes.Superheated steam (SHS) has been used as a carrier gas for pressurized steam torrefaction, steam explosion or pyrolysis, but is barely used as a heat source. However, SHS is superior in thermal capacity and heat transfer coefficient resulting in even heating and fast heating rates. Therefore, this work applied SHS as the sole heat source for torrefaction at ambient pressure. A setup was specially designed and capable of heating wood shavings at a rate &gt;120 °C?min-1. Solid products were analyzed in many aspects and demonstrated the enhanced organics conversion owing to SHS torrefaction. Torrefied biomass was comparable to slow pyrolysis char in fuel quality and superior to that of conventional torrefactions. Moreover, SHS torrefaction was super-timesaving. A coal-like product (HHV of 27.84 MJ?kg-1) was achieved in only 15 min at 350 °C. Overall, SHS torrefaction boosted biomass densification and gaveriseto greater production efficiency.Efficient sampling with swabs is crucial for optimal forensic DNA analysis. The DNA recovery is determined by the skill of the practitioner and the compatibility between the applied swab and the surface. Here we investigate the impact of swabbing technique and swab type on the DNA yield. Thirteen different swabs from four categories (cotton, flocked nylon, small foam and large foam) provided equal DNA yields for smooth/non-absorbing surfaces. Large foam swabs gave higher DNA recovery for an absorbing wood surface. Factorial design of experiments and ANOVA was applied to study swabbing techniques for cotton swabs. Two key factors for efficient sampling were found to be 1) holding the swab with an approximate 60° angle against the surface and 2) to rotate the swab during sampling. For absorbing wood, it was beneficial to wet the swab heavily. The results of the factorial experiments were used to develop swabbing protocols for different surfaces. When ten experienced practitioners sampled according to these protocols, the DNA yield was increased for ridged plastic (around 1.25 times more DNA) and absorbing wood (2.2-6.2 times more DNA). For window glass, representing a smooth/non-absorbing surface, sampling according to the protocol gave DNA yields equivalent to applying individual sampling techniques. The protocol lowered person-to-person variation for ridged plastic. In conclusion, we have developed instructive protocols for cotton swab sampling on three types of surfaces smooth/non-absorbing, ridged/non-absorbing and smooth/absorbing. We believe that such swabbing protocols will streamline and simplify the training of new practitioners and improve sampling efficiency for invisible DNA residues in casework.Graduate nursing students experience considerable stress due to their multiple responsibilities, including professional responsibilities, graduate coursework and family commitments. Peer support can help graduate students overcome stress and may heavily influence their learning satisfaction. However, the mechanisms underlying the influence of peer support on learning satisfaction in graduate students remain unclear. Thus, this cross-sectional study examined the relationship between peer support, achievement emotions (learner-specific emotions related to achievement activities) and learning satisfaction, as well as the mediating effects of achievement emotions among 225 graduate nursing students working in the Korean health care system. Participants completed a questionnaire assessing these variables. Pearson correlation was conducted to investigate the relationship between the variables and Baron and Kenny's regression analysis and Sobel test were conducted to examine the mediating effects of achievement emotions. Peer support correlated positively with positive achievement emotions and learning satisfaction and negatively with negative emotions. Positive emotions were positively and negative emotions were negatively, correlated with learning satisfaction. Achievement emotions mediated the relationship between peer support and learning satisfaction. Our findings indicate that peer support plays an important role in improving learning satisfaction, emphasizing the advantages of positive emotions and the disadvantages of negative emotions in graduate nursing students.Despite evidence of the impact of discharge teaching on patient outcomes, nursing students are poorly prepared in the pedagogical skills necessary for their role as patient and family educators in clinical practice. This study evaluated the effectiveness of simulation combined with online learning to improve nursing students' discharge teaching skills.
The module included simulations before and after an online module on patient/family teaching for hospital discharge. https://www.selleckchem.com/products/glutathione.html Evaluation measures were student and independent rater evaluations using the Quality of Discharge Teaching Scale- Evaluation form (QDTS-E).
Students (n=153) improved their performance on both content and delivery subscales of the QDTS-E by 20% (student self-evaluations) and 18% (independent raters). However, correlations between student and rater scores were low (r=0.08-0.22).
Use of simulation with online learning in a discharge teaching module can help students build patient education skills to improve post-discharge patient outcomes, contributing to national health priorities to reduce hospital readmissions.
